PUMPING APPARATUS.

Application filed March 39, 1923. Serial No. 628,784.

To all whom it may concern:

Be it known that I, OswALD J. TURNsEK, a citizen of the United States ofAmerica, residing at Stuttgart, in the county of Arkansas and State ofArkansas, have invented certain new and useful Improvements in PumpingApparatus, of which the following is a specification. My presentinvention relates generally to pumping apparatus, and more particularlyto pump heads, and proposes a pump. rod actuating mechanism by means ofwhich a long stroke reciprocating motion may be developed having specialadvantage both in regard to the actuation of the pump rod in use and tothe maintenance of the pump and the actuating parts against undue wearin use as well as rapid deterioration between periods of operation,myfurther object being the provision of a compact structure which isreadily accessible to and easy and quick repair and substitution ofparts as well as an apparatus which readily lends itself to encasementtopermit of the run ning of its main components in a fluid lubricant.

In the accompanying drawings which illustrate my present invention andform a part of this specification,

Figure 1 is a front elevation showing my improved pump apparatus, withthe front plate of the casing removed,

Figure 2 is a side elevation,

Figure 3 is an enlarged perspective view of certain. parts removed,

Figure 4 is a detail perspective view of a portion of one of theactuating chains, and

Figure 5 is a longitudinal section through the pump rod and its sleeveshowing the trunnion connections thereof.

Referring now to these figures and particularly to Figure 1 I have shownmy improved apparatus in connectlon with a pump casing 10 havlng thereinupper and lowerv plungers 11 and 12, working in opposition to oneanother, both of these plunger-s being valved and the lower plunger 12being mounted upon the lower end of the pumprod 13, while the upperplunger 11 is mounted upon the lower end of a sleeve 14 around thepumprod and through which the latter is movable. V

I havev also shown the pump casing 10 with a Y fitting 15 at its upperend, the breed 91 which term the outlet, and.

the upper end of the main section of which supports a stufling box andthe like 17 upwardly through which the sleeve 14 or rather also includesside walls 25' formed by the upper portions of side frames 26. Theseside frames are securely mounted at their lower ends upon the sideportions of a base plate 27, the latter of which surrounds the stuflingbox at theupper end of the pump casing so that thevertically shiftablepump rod and its sleeve will not only be guided in their movement abovethe ground level or the upper end of the pump casing, but a frame willbe formed which, by the addition of front and rear walls in connectionwith the side walls 25 and the vertically spaced top and bottom plates23 and 24, become a casing wherein the pump rod andsleeve actuatingparts may, to a considerable extent, be completely housed and provisionlikewise made for the running of these parts in a fluid lubricant. H p

' To this end the side frames 26 have side bearings 28 for a transversedriven shaft 29 able source of powerp This shaft 29 has upon its outerportions, outwardly beyond thebearings 28,small pinions 30 in engagementwith comparatively large gears 31 secured upon the outer portions ofstud shafts 32 mounted in bearings 33 upon the side walls 25 of thecasing and also extending inwardly through these side-walls and prosvidedwith inner sprockets 34 around which the lower portions of flexiblechains and the like 35 extend.

The upper sleeve section 18 has an elongated vertical slot 36 above theupper end of the pump casing, through which a trunnion 37 exte'ndsfroman attaching plate 38 securely bolted as by means of bolts 39 shown inFigureb, to the upper rod section so, eaidattaching plate -38-" and.saidrod.

,posite sides of the upper-portion of the section being provided Withrelatively engaging cross lugs and slots.

Diametrically outstanding therefrom with respect to its slot 36, theupper sleeve section 18 has a trunnion 4L0 projecting from an attaching;plate 41 "which latter is securely riveted to the sleeve as shown inFigure 5.

As seen particularly in FigureS't-he trrlnnions 37 and are securelyfastened to the horizontal hearing end portions '42 of a pair ofhorizontally disposed cross heads 43 "and 44, whose opposite ends havevertical bearingporti'ons 45 disposedon and slidahle in connection witha pair of upright guide rods 46, disposed laterally spaced relation "andsecured at itheirupper and lower" ends through the top and Ebnttomplates 23 cand' fle. p i v IE ach' of the cross heads 43 and fe l has:an "internal slide lbl'ock 47mm B le "therein at right angles to theline of :-movement o-1'" pumprod, and each cross head also has adet'a'chab-le rail .48 above its slide :block wherehythe latter mayheireadily reached, and wear compensated for; Each slide block 47 has anopening 49, and each of the actuating chains 50 includesin its length apin block 51 having a laterally projecting pin '52 x as most plainlyseen in Figures, which pinlis journaled. in the fresp ective slideloloclropenin-g 49.

The chains 50 which ZLIQzlDOSllZlOllGdiQt oppump rod and its sleeve, andthe'lower portions of which extend around the beforeme-ntioned sprockets.34, have their upperv ends extending around sprockets'53 upon the innerendsof sh'afts h journaled through willzbe alternately the side plates25 of the'casingzand through bearing :mernbers "55 secured .tothe. sidewalls. I

It is thus obvious that are rotated the cross heads ABJand 44 will .beraised and lowered oppositely with refspect :to oneanother andcorrespondlng movements communicated .to the pump'rod and its sleevewhereby the pilungers l'l and '12 shifted toward and away from oneanother. v

The major porti'oniof :therqperating parts,

' that is including the chains 50 --and their connections whereby theyimpart along ,stroke movement to; the pump $96. and its s sleeve, arelocated Within the leasing and between ithei top .and bottom plates .23land :50 that these 1 parts may conveniently run in oili-andjgyet remainreadily accessible for purposes of repair and substitution of parts,these disadvantages being supple- :mecntal to-and beyond the more.iinip'ortant advantages resulting from i the [application :tectiveness,aniieeflieiency sinfop erationandat the same time materially increasethe strength anddurahility ofthe several parts and promote an apparatuswhich will be economical in first cost and practically eliminate theexpensive upkeep of pumping app aratus now in common use.
